Abstract

Es wird ein Verfahren zur Korrektur objektivabhängiger Linearitäts- und Deckungsfehler bei einer Farbfernsehkamera vorgeschlagen. Hierbei werden entsprechend der Objektivein­ stellung repräsentative Signale abgeleitet, digitalisiert und bil­ den die Adresse für einen Korrekturwertspeicher, der für jede Objektiveinstellung Korrekturwerte abgibt, die digital/analog gewandelt und als Korrektursignal den Horizontal- und Verti­ kal-Ablenksignalen wenigstens einer Aufnahmeröhre zuge­ führt werden. It becomes a procedure for correcting lens-dependent Linearity and coverage errors in a color television camera suggested. Here, the lens will be position representative signals derived, digitized and bil the address for a correction value memory, which for each Lens setting outputs correction values that are digital / analog converted and as a correction signal the horizontal and vertical Kal deflection signals at least one receiving tube leads.
